Overview

Physicochemical analysis shows improved growth and gut health in piglets, highlighting dietary fiber's role post-weaning.

Key Points

  • To evaluate the effects of milled almond shells as a fiber source in weaned piglet diets.
  • Physicochemical analysis of milled almond shells at different particle sizes.
  • Feeding trial with 2.5% milled almond shells compared to 8% wheat bran in piglet diets.
  • Assessment of growth performance, intestinal morphology, and microbial composition after 14 days post-weaning.
  • Piglets on almond shell diets had higher final body weight and average daily gain compared to wheat bran.
  • Increased villus surface area and mucosal thickness were observed in the intestines of almond-fed piglets.
  • Reduced abundance of Proteobacteria and higher total volatile fatty acid production in almond shell groups compared to wheat bran.
